People with alopecia areata typically have smooth, round patches of complete hair loss that develop over a period of a few weeks, followed in most cases by regrowth over several months (picture 1). However, alopecia areata may persist for several years and sometimes hair never regrows.
It can occur suddenly or develop gradually over time. Sudden-onset causes include illness, diet, medications, and childbirth. Alopecia that has a gradual onset more likely has a genetic component.
The condition is unpredictable, and the cycle of hair loss and regrowth can repeat itself. Alopecia areata can grow into another form of alopecia. In its worst form, alopecia universalis causes you to lose all body hair. This includes eyebrows, eyelashes, arms, legs, underarms, pubic, and chest and back hair for men.
Alopecia areata is an autoimmune disorder that causes your hair to come out, often in clumps the size and shape of a quarter. The amount of hair loss is different in everyone.
The only sign of alopecia areata is often sudden hair loss. The patches of hair loss can grow larger. Sometimes, the patches grow larger and become one large bald spot.
Patchy hair loss (alopecia areata)
In the type of patchy hair loss known as alopecia areata, hair loss occurs suddenly and usually starts with one or more circular bald patches that may overlap.
Alopecia areata typically begins with sudden loss of round or oval patches of hair on the scalp, but any part of the body may be affected, such as the beard area in men, or the eyebrows or eyelashes.
The extent of alopecia (how much hair has fallen out) varies and links to the different subtypes. Some said their hair loss involved one small patch about the size of a 1p coin which regrew after a few weeks or months. Others developed more patches which sometimes joined up into bigger bald areas over time.
Thankfully, mild cases of alopecia areata often get better without treatment within a few months to a year. In some cases, patchy baldness may come and go over many months or years. The size of the bald patch or patches and how long they last are quite variable.
This type of baldness is not usually caused by a disease. It is related to aging, heredity, and changes in the hormone testosterone. Inherited, or pattern baldness, affects many more men than women. Male pattern baldness can occur at any time after puberty.
Alopecia areata affects people of all ages including young children. It produces circular patches of hair loss that appear overnight. More patches appear over time and eventually about 5% of people affected lose every hair on their body.
1) Yes, alopecia areata can pass from parents to children - but it is not common. About 6 % of your son's children would be predicated to have alopecia areata and 94 % would not. In other words, it' s possible for your son to have a child with alopecia areata but most likely he will not.
When does alopecia areata begin? You can get alopecia areata at any age; however, most people develop it by 30 years of age. For many, the disease begins during childhood or the teenage years.
Conclusions and Relevance Patients with alopecia areata have a higher risk of mortality associated with self-harm, psychiatric diseases, and smoking-associated malignant diseases including lung cancer.
Is alopecia contagious? Alopecia is not contagious. Individuals who develop alopecia areata typically have both a family history and some type of environmental trigger, such as emotional or physical stress.
On the AIP elimination diet, you will avoid grains, legumes, nightshades (such as potatoes and peppers), dairy, eggs, coffee, alcohol, sugar, oil and food additives. After a few months, you can work the excluded foods back in one at a time to figure out which foods trigger an inflammatory reaction.
Avoiding unnecessary hair or scalp trauma, reducing stress and analyzing your diet are all worthwhile endeavors when attempting to prevent alopecia areata from spreading.
Sudden Loss of Patches of Hair
Bald spots may grow very slowly in one area or you may notice a patch or strip of hair loss that appears within just a day or two. In some cases, you may notice burning or stinging before sudden hair loss.
Everyone is born with hundreds of thousands of hair on the head. The hair cycle consists of three phases: the growth phase, which is called anagen, the resting phase, which is called catagen, and the shedding phase, which is the telogen phase.
The Ludwig scale defines three broad stages of hair loss. In stage 1, the hair on the top of the head begins thinning. In stage 2, the scalp starts to become visible. In stage 3, all of the hair at the crown may be lost, resulting in baldness.
Hair usually falls out in patches on the scalp. These patches are often several centimeters or less. Hair loss might also occur on other parts of the face, like the eyebrows, eyelashes, and beard, as well as other parts of the body. Some people lose hair in a few places.
